* Metric Name: Fire Ignition Probability, Lightning-Caused  

* Tier: 3  

* Data Vintage: 1992 to 2015  

* Unit Of Measure: Probability, 0-1  

* Represent element and pillar: No  

* Type and distribution of data: Bimodal distribution representing probability. **** Raw data values range from 0 to 0.957.  

* Translation: Where is lightning-caused fire ignition probability high?  

* Translation method and outcome: Raw data values translated to range from +1 to -1 representing more favorable to less favorable conditions, respectively. The proposition of more favorable is based on the objective of higher lightning-caused ignition probability (positive linear slope). More favorable (translated to +1) > 0.957, less favorable (translated to -1) set at 0.
